Lab-grown diamond quality
D–F colour · VS1 clarity or better
Every lab-grown diamond is D–F colour and VS1 clarity or better. Round brilliant lab-grown diamonds can receive a formal cut grade; fancy shapes are assessed through their proportions, polish, symmetry and overall make. Any piece whose centre stone, on its own, weighs 1.00ct or more includes an individual IGI grading report as standard. Total carat weight does not count towards this.
The square at Theodora's centre sets the tone: clear, strong and impossible to mistake. From it, round stones travel along the shoulders and through the setting, turning one bold geometry into a richly detailed whole. This is an engagement ring for someone who wants precision at the centre and abundance around it.
A 6.90 x 6.90mm princess cut lab-grown diamond weighing 2.00ct commands the design. Twelve 3.00mm and forty-four 1.30mm round lab-grown diamonds then build the surrounding light, bringing the count to fifty-seven. The contrast between the square centre and repeated circles gives Theodora its scale, structure and unmistakable character.
Theodora combines a substantial princess cut centre with extensive round detail, so the design feels complete from the head into the shoulders. All fifty-seven lab-grown diamonds are D to F colour and VS1 clarity or better, with an independent IGI grading report for the centre. Choose 14kt for the harder, more scratch-resistant gold, or 18kt for more pure gold and a heavier feel. Three gold colours are available.
This ring is made to order in your size. Choose your UK ring size when you order — there is no extra charge for any size. If you are unsure of your size, our ring sizer makes it easy at home — and your £5 comes straight back to you as a gift card. Standard UK sizes are available — if you need guidance, contact us before placing your order.
Every piece is crafted to your chosen metal and size. Our usual timeline is around four weeks from order to dispatch, which includes UK hallmarking where required. More complex pieces may take slightly longer. We confirm the expected timeframe in writing before production begins.
Theodora is designed to be the clear focus, so wear it alone when you want every shoulder stone visible. If adding a second ring, keep it plain and restrained beside the detailed setting. White, Yellow or Rose Gold lets the strong square centre sit within your preferred jewellery palette.
What size is Theodora's princess cut lab-grown diamond?
The centre lab-grown diamond measures 6.90 x 6.90mm and weighs 2.00ct. Its square princess cut is accompanied by fifty-six round lab-grown diamonds distributed along the shoulders and through the setting.
What round lab-grown diamonds are used in Theodora?
The design contains twelve 3.00mm and forty-four 1.30mm round lab-grown diamonds, alongside the princess cut centre. That brings the full stone count to fifty-seven, all D to F colour and VS1 clarity or better.
Does Theodora come with certification and a guarantee?
